freaking out!! TMI! please help!!

I just found a bump in the outer side of my lip of my v! I don't know what it is and I'm freaking out! I've only been with one person and it was my ex and haven't had been with anyone in 4 months and I don't know what it is! It's really scaring me and I think I irritated it (by squeezing it)😣I don't know what to do !
It looks like the bumps you get from shaving and when it gets irritated but I don't know! 😞
Picture makes it look worse😓😥
